Users over 70 years old and stress level during sleep.

Good morning,
I would like to compare the stress graphs of my parents with other users of the same age or older because they both have a high level of stress during the day and in the early stages of sleep.

I would like to understand if it is a characteristic of their age, thanks to anyone who can collaborate by posting the body battery graph of some days (the body battery graph also contains the stress level)
